General rules for car boot liner
A moulded liner is the easiest surface in this whole subject. It comes out, it holds the spill inside its lip, and it can be washed with a hose on the drive.
That is the point of owning one, so use it: lift the liner out with the mess still in it rather than trying to clean it in place, and check whether anything got past the lip into the boot carpet underneath.
Solvents and very hot water can soften or distort TPE, so warm soapy water and a brush is the whole method.
Check the label
Most boot liners are moulded rubber or TPE with a raised lip, which is exactly what they are for. If yours is a carpet type liner rather than a moulded tray, treat it as car carpet instead, because the two behave nothing alike.

A boot liner is the one item here designed for this exact event.
The lip does the work
A moulded liner has a raised edge on all four sides, so a spill stays on the liner instead of reaching the boot carpet. Lifting it out carefully, keeping it level, is the single most useful thing you can do.
The material is forgiving
Rubber and TPE are non porous. Nothing soaks in, so nothing needs drawing out, and warm soapy water with a brush removes everything. Very hot water and strong solvents are the only real risks, because both can soften or distort the moulding.
Check underneath
Liners are cut close to the boot floor but not sealed to it. Liquid that went over the lip or through a seat pass through is now on the boot carpet, which is a different job.

Carpet tile maintenance guidelines, Interface
manufacturer
Carpet manufacturer's maintenance guidance to blot a spill with a clean white cloth working from the edge towards the centre, never rub a wet spill, keep spotting solutions between pH 4.5 and 8.5 and away from aggressive solvents, and use as little water as possible because over wetting causes rapid resoiling and fibre damage.

Sick happens: how to get vomit out of carpet, National Carpet Cleaners Association
trade body
UK carpet cleaning trade body method for vomit: scrape solids with a blunt spatula or spoon, apply equal parts white vinegar and water, blot gently working towards the middle of the mark rather than outwards, never scrub because that drives the vomit deeper and damages the carpet, use only a small amount of warm water on a dried mark, and expect rehydrating it to release the smell again so ventilate.
